FIELD OF THE DISCLOSURE

The present disclosure relates in general to systems and methods for displaying content, and more specifically to systems and methods for presenting content based on ocular, head, and expressive feedback.

BACKGROUND

People consume an ever increasing amount of text and other media daily. As such, numerous efforts have been undertaken to improve the tools at the disposal of readers when displaying content, especially tools to allow people to read more quickly while sustaining a high level of reading comprehension. Examples of such tools include speed reading techniques and Rapid Serial Visual Presentation (RSVP) text display techniques. Tools and techniques relating to Rapid Serial Visual Presentation are further described within de Bruijn, Oscar, and Robert Spence. “Rapid serial visual presentation: a space-time trade-off in information presentation.” Advanced visual interfaces. 2000.

Though these and other efforts have attempted to provide people with better tools for the consumption of media, there is a general trade-off between comprehension and the ability to consume media quickly, access supplemental content and control displayed content. As such, there is a continuing need to develop techniques to improve comprehension and control displayed content.

As people use electronic devices to review content, content can be display in an automated manner, but such automated systems do not account for variations in a viewer's comprehension. It is desirable to have a system that can display the content to allow for the user to consume the content in an efficient manner, including dynamically adjusting for instances where the person has slowed or stopped consuming content, is distracted, or requires more information. It is also desirable to have a system that can permits a user to easily navigate and control the displayed content.

FIG. 1 is a functional block diagram illustrating a system architecture for presenting supplemental content to a user based on at least one of head, ocular or expressive feedback and the displayed content.

In FIG. 1, system architecture 100 includes user device 110, external data source 132, and communications network 134. In FIG. 1, user device 110 includes communication module 112, input/output (I/O) module 114, user interface 116, tracking module 118, tracking sensor module 120, and content processing module 128. A user 130 interacts with and uses system architecture 100. The user device 110 is operably coupled to and in bi-directional communication with external data source 132 via communications network 134. In some embodiments, user interface 116 and tracking sensor module 120 are configured to operate with associated hardware (not shown, but described in FIG. 3, below) to interact with user 130. In other embodiments, system architecture 100 can include additional, fewer, or differently arranged components than those illustrated in FIG. 1.

The user device 110 can comprise one or more tracking modules and one or more tracking sensor modules. The tracking module 118 is shown in FIG. 1 as an eye-tracking module, but the tracking module 118 can be an eye-tracking module, a head-tracking module, and/or an expression-processing tracking module. The tracking sensor module 120 can be an eye-expression sensor module, a head-tracking sensor module, or an expression processing sensor module. Although FIG. 1 recites an eye-tracking module and an eye-tracking sensor module, it is intended that any tracking module or additional tracking modules can be used in the user device 110. In an example, the system architecture 100 can include any combination of two or more of an eye-expression module, a head-tracking module or an expression processing module and two or more of a tracking sensor module corresponding to the tracking modules employed in the system architecture. In yet other embodiments, components within system architecture 100 may be implemented on any type of suitable processor-controlled device that receives, processes, and/or transmits digital data, and is configured as further described in FIG. 3, below. Examples of devices incorporating one or more suitable processor-controlled devices for executing software for presenting content based on head, ocular, and expressive feedback include smartphones, desktop computers, laptop computers, servers, tablets, PDAs, and the like.

In some embodiments, user device 110 is implemented as a computing device including hardware and/or software modules configured to track and characterize the head position, gaze, and/or expression of user 130. In an embodiment, the characterization of the head position, gaze, and/or expression of user 130 generates a request for supplemental content from user 130. In this embodiment, the user device retrieves external supplemental content data from external data source 132 and processes the received external content data to produce supplemental content and displays supplemental content to user 130.

The user 130 is an end-user of user device 110 that provides input to user device 110 in order to consume content and supplemental content. In an embodiment, the input is behavioral data via a sensor module. In an embodiment, the supplemental content is associated with the displayed content. In an example, user 130 is a consumer reading reference information regarding one or more products offered by an insurance company that wishes to read additional content related to the currently displayed content. In another example, user 130 is a person in the legal industry reading reference information regarding one or more areas of law that wishes to read additional content related to the currently displayed content. In another example, user 130 is a person reading reference information regarding one or more areas related to home and gardening including cooking, and do-it-yourself projects that wishes to read additional content related to the currently displayed content. In the foregoing examples, the supplemental content is displayed based on the behavioral data. In the foregoing examples, the supplemental content is relevant to the currently displayed content.

In some embodiments, communication module 112 is implemented as a software module running on associated hardware, further detailed in FIG. 3, that is configured to receive command data from content processing module 128, process the received command data to produce query data, provide the query data to an external data source 132, receive result data from external data source 132, process the received result data into external content data, and provide the external content data to content processing module 128. In other embodiments, communication module 112 is further configured to process the received result data into external data and to provide the external data to content processing module 128 to be displayed to the user as supplemental content. In some embodiments, the supplemental content is relevant to the currently displayed content.

In some embodiments, communication module 112 sends and receives data via a wired or wireless connection using a desired protocol (e.g., TCP/IP, HTTP, UDP, IMAP, and the like). In some embodiments, query data includes requests for external content data contained within command data. In an example, query data includes a request for one or more supplemental content related to the displayed content. In an example, the supplemental content includes text and/or media (e.g., RSVP text, images, audio, video, and the like) or the like related to the displayed content or a portion of the displayed content. In other embodiments, query data includes requests for supplemental data specified within command data. In these embodiments, query data includes a request for a definition of one or more terms in content presented to user 130, a request for media associated with the one or more terms, and the like. Optionally, the supplemental content can be additional information on terminology within the displayed content or the supplemental content can be a response to content navigation request. For example, if the displayed content is a life insurance policy the supplemental content may be terminology for various types of life insurance policies. In another example if the displayed content pertains to legal information, the supplemental content may be cases, laws or regulations referenced in the displayed content. In another example if the displayed content pertains to a cooking recipe, the supplemental content may be nutritional information, measurement conversions or ingredient substitution information. Optionally, the supplemental content may contain a hyperlink to additional content related to the supplemental content. If the system detects that the user has a state of discontent, confusion, unhappiness, etc. that the user has shifted its gaze or changed the position of its head, the system can display supplemental content related to the displayed content so that present content may be easier to understand or more interesting.

In other embodiments, input/output module 114 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive input data from the tracking module 118 and/or the tracking sensor module 120 to process the received input data into instruction data, and to provide the instruction data to content processing module 128. In these embodiments, input/output module 114 is further configured to receive output data from content processing module 128, process the received output data to generate content, and display the generated content to the user as supplemental content on the display of the user device 110. In some embodiments, the supplemental content is relevant to the currently displayed content.

In some embodiments, instruction requests are one or more of requests for content associated with currently displayed content. In an example, instruction data includes requests for additional content related to at least a portion of content on an electronic document (e.g., a section of an insurance policy, contract, and the like) being displayed to the user. Optionally, the instruction requests are generated based on the tracking at least one of the head position, gaze, or expression of the user. For example, if the head position or gaze of the user indicates the user is focused on a portion of the user interface 116 that contains the displayed content, supplemental content related to the displayed content will be generated and displayed to the user.

In some embodiments, user interface 116 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive input from user 130, processes the received input into input data, provide the input data to input/output module 114, receives content from input/output module 114, and displays content to user 130. In these embodiments, input data includes user requests to display a desired set of supplemental content relevant to the content currently being viewed.

In the example shown in FIG. 1, tracking module 118 is an eye tracking module that is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive command data from content processing module 128, process the command data into hardware operation data, and provide the hardware operation data to eye-tracking sensor module 120. In these embodiments, eye-tracking module 118 is further configured to receive ocular sensor data from eye-tracking sensor module 120, processes the ocular sensor data to generate ocular engagement data, and provides the ocular engagement data to content processing module 128. Further to these embodiments, ocular engagement data includes one or more metrics characterizing the level of engagement of user 130 with content being displayed via user interface 116. In an example, the ocular engagement data includes data describing whether or not the gaze of user 130 is directed toward the content displayed via user interface 116, a general level of interest in the content displayed via user interface 116 as determined by the eye movements of user 130, and the like. In these embodiments, hardware operation data includes instructions for hardware operation, such as instructions to activate eye-tracking sensors, to begin to track the gaze of user 130, to stop tracking the gaze of user 130, and the like.

In some embodiments, tracking sensor module 120 is an eye sensor tracking module which is implemented as software configured to control associated hardware, further detailed in FIG. 3, and configured to receive hardware operation data from eye-tracking module 118, interact with user 130 in order to generate ocular sensor data, and provide the ocular sensor data to eye-tracking module 118. In these embodiments, ocular sensor data includes data describing the movement of the eyes of user 130. In an example, eye-tracking sensor module 120 is implemented as software configured to control camera hardware (e.g., a camera pair, not shown) included within user device 110 that is configured to determine the direction of the gaze of user 130. In this example, ocular sensor data includes the length of stare of user 130 on one or more regions of content being displayed via user interface 116, whether or not user 130 is looking at one or more portions of content being displayed via user interface 116, and the path of the gaze of user 130 as user 130 views content being displayed via user interface 116.

Eye tracking module 118 may utilize sensor or camera data to determine the gaze of a user. In one embodiment, a light (e.g., infrared) is reflected from the user's eye and a video camera or other sensor can receive the corneal reflection. The eye tracking module 118 analyzes the ocular sensor data to determine eye rotation from a change in the light reflection. A vector between a pupil center and the corneal reflections can be used to compute a gaze direction. Eye movement data may be based upon a saccade and/or a fixation, which may alternate. A fixation is generally maintaining a visual gaze on a single location, and it can be a point between any two saccades. A saccade is generally a simultaneous movement of both eyes between two phases of fixation in the same direction.

In one implementation, the eye tracking module can use a dark-pupil technique, whereby if the illumination source is offset from the optical path, then the pupil appears dark as the retroreflection from the retina is directed away from the camera. In another implementation, the eye tracking module can use a bright-pupil technique, whereby if the illumination is coaxial with the optical path, then the eye acts as a retro reflector as the light reflects off the retina creating a bright pupil effect.

In another embodiment, a camera or sensor can track eye image features (e.g., retinal blood vessels) and follow the features as the eye rotates. It is preferable that the eye tracking data is obtained in a manner that is non-invasive.

In yet another embodiment, a camera or sensor can identify a location of an iris or pupil based on the circular shape or by detection an edge. The movement of the iris or pupil can then be detected.

An expression processing module can be an eye-tracking processing module or a head tracking module. In some embodiments, the expression processing module 122 can use a coding system that recognizes eye movement and/or gaze direction and generates a score based on duration and direction. Eye movement or gazing may have a duration of about 1/25 of a second to 2 seconds or longer, so the expression processing module 122 will receive a data feed of eye movements from a high speed camera having increments of less than one second to account for very quick changes. Some micro-eye movements occur so quickly that a human observer cannot detect or sense the shift in gaze or eye movement. In one embodiment, supplemental content will be displayed when the eye movement meets a threshold value, when the gaze is directed away from the displayed content, or both.

In some embodiments, the tracking sensor module 120 is a head tracking sensor module which is implemented as software configured to control associated hardware, further detailed in FIG. 3, and configured to receive hardware operation data from head-tracking module 118, interact with user 130 in order to generate head position data, and provide the head position data to head tracking module 118. In these embodiments, head position data includes data describing the movement of the head of user 130. In an example, head-tracking sensor module 120 is implemented as software configured to control camera hardware (e.g., a camera pair, not shown) included within user device 110 that is configured to determine the position of the head of user 130. In this example, head position data includes the position of the head of user 130 with respect to one or more regions of content being displayed via user interface 116, whether or not user 130 is looking at one or more portions of content being displayed via user interface 116, and the path of the head movement user 130 as user 130 views content being displayed via user interface 116.

Head tracking module 118 may utilize sensor or camera data to determine the initial head position of a user and any subsequent change from the initial head position. In one embodiment, a light (e.g., infrared) is reflected from the user's head and a video camera or other sensor can receive the reflection from the user's head. The head tracking module 118 analyzes the head position data to determine head movement from a change in the light reflection. A vector between a location on the user's head and the head reflections can be used to compute a change in head position or direction. Head position data may be based upon a movement and/or a fixation, which may alternate. A fixation is generally maintaining a head position in single location. A movement is generally any change in position of the head from an initial position.

In one implementation, the head tracking module can use a marker technique, whereby if the illumination source is offset from the marker on the user movement is determined.

In another embodiment, a camera or sensor can track head image features (e.g., how much of the head is shown, if only a portion of the head e.g. a cheek or the top of the head) and follow the features as the head rotates or moves. It is preferable that the head tracking data is obtained in a manner that is non-invasive.

In some embodiments, an expression processing module 122 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and is configured to receive command data from content processing module 128, configured to process the command data into hardware operation data, and configured to provide the hardware operation data to expression sensor module 124. In these embodiments, expression processing module 122 is further configured to receive expression sensor data from expression sensor module 124, process the expression sensor data to generate emotional state data, and provide the emotional state data to content processing module 128. The expression sensor data represents a micro-expression of the user, which can be a brief, involuntary facial expression that is shown on the user's face while the user is experiencing the emotion.

Further to these embodiments, emotional state data can be processed to generate data describing the emotional state of user 130. In an example, emotional state data describes whether or not user 130 is confused by content being displayed via user interface 116. In this example, the emotional state data can be generated by implementing methods similar to those described in Chiu, Mei-Hung, et al, “The role of facial microexpression state (FMES) change in the process of conceptual conflict.” British Journal of Educational Technology 45.3 (2014): 471-486. In these embodiments, hardware operation data includes instructions for hardware operation, such as instructions to activate expression sensors, to begin to track the expression of user 130, to stop tracking the expression of user 130, and the like.

In some embodiments, expression sensor module 124 is implemented as software configured to control associated hardware, further detailed in FIG. 3, and configured to receive hardware operation data from expression processing module 122, interact with user 130 in order to generate expression sensor data, and provide the expression sensor data to expression processing module 122. In these embodiments, expression sensor data includes data describing micro-expressions of user 130 (e.g., expression skeletons describing facial states, and the like). In an example, expression sensor module 124 is implemented as software configured to control a camera, not shown, included within user device 110 that is configured to detect the micro-expressions of user 130. In this example, expression sensor data includes images of user 130 as user 130 views content displayed via user interface 116.

The expression processing module 122 can use a facial action coding system that recognizes changes in a facial expression and generates a score based on duration, intensity, and asymmetry. Facial expressions may have a duration of about 1/25 to 1/15 of a second, so the expression processing module 122 will receive a data feed of facial movements from a high speed camera having increments of less than one second to account for very quick changes. Some micro-expressions occur so quickly that a human observer cannot detect or sense the expression. In one embodiment, the expression processing module may require a threshold amount of time that a user holds a particular expression (e.g., 1/25 second, ¼ second, ⅓ second, ½ second) before adjusting content in view of that expression. In order to capture only micro-expressions, the expression processing module may also include a threshold of a maximum amount of time for that particular expression (e.g., ½ second, ⅔ second, ¾ second, 1 second, 1.5 seconds). In an alternative embodiment, the expression processing module is not limited to only micro-expressions.

In one embodiment, the tracking processing module may require a threshold amount of time that a micro-expressions or expression is maintained (e.g., 1/25 second, ¼ second, ⅓ second, ½ second) before displaying supplemental content.

In one example, the expression processing module may receive data from a camera or other sensor and process the data to determine that the user is in a state of disgust based on the expression sensor data. Data that may be relevant to determining the state of disgust can include data that represents that the user has raised an upper lid, raised a lower lip, wrinkled the nose, raised cheeks, and/or lines below the lower lid. In another example, a state of anger may be associated with a profile having data that represents lowered eyebrows, a wrinkled forehead, tensed eyelids, and tensed lips. A file containing a set of profiles, which may be stored in a database (not shown) associated with the server 240, may be used to match the expression sensor data by converting the data to generate action unit scores of the facial action coding system and then determining a similarity to any stored profiles.

Upon receiving this data, the expression processing module compares this data to stored profiles and can determine that this data matches a profile of disgust or confusion. Based on this determined profile, the system may generate additional content based on the content that was being viewed in association with this state or respond to an instruction request. In an embodiment, the additional content may be stored in a database and tagged with a particular state, such that if the user is disgusted with a price or confused about a term, additional content can be displayed that justifies the price or offers alternative pricing schemes or provides supplemental content about a term. Optionally, the supplemental content can be additional information on terminology within the displayed content. For example, if the displayed content is a life insurance policy the supplemental content may be terminology for various types of life insurance policies. In another example if the displayed content pertains to legal information, the supplemental content may be cases, laws or regulations referenced in the displayed content. In another example if the displayed content pertains to a cooking recipe, the supplemental content may be nutritional information, measurement conversions or ingredient substitution information.

In some embodiments, content processing module 128 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive user instruction data from input/output module 114, receive one or more of ocular engagement data from eye-tracking module, receive head position data from the head position tracking module and/or receive emotional state data from expression processing module or head position data from a tracking module 118, process one or more of the head position data, ocular engagement data, and/or emotional state data to generate command data, and to provide the command data to the communication module 112. In these embodiments, content processing module 128 is further configured to receive external content data from communication module 112, to retrieve internal content data from a storage device associated with user device 110 (further detailed in FIG. 3), and process said external content data and internal content data to generate output. Further to these embodiments, content processing module 128 is configured to receive supplemental external data from communication module 112, to retrieve supplemental internal data from the storage device associated with user device 110, and process the supplemental external data and the supplemental internal data to generate output data. In an embodiment, the output data is a response to command data. In an embodiment, the output data is generated based on collected behavior data.

In some embodiments, command data includes instructions for a communications module to retrieve data specified within user instruction data. In some embodiment, command data includes instructions for a communications module to retrieve data based on collected behavior data. In some embodiments, command data includes instructions for a communications module to retrieve data when a threshold value is met. In an example, command data includes instructions associated with communication module 112 for it to generate a desired query data. In these embodiments, command data includes instructions for module 118 and processing module 122 to present supplemental content, navigate the content (e.g. pausing the displayed text, resuming the displayed text, scrolling through the text, skipping forward or rewinding in the content and the like) and present the content.

Further to these embodiments, supplemental internal content data includes text, images, and other media stored within a storage device associated with user device 110. In these embodiments, supplemental internal data includes text, images, and other media that is supplemental to content currently and/or previously presented to user 130. Still further to these embodiments, output data includes text, images, video, and layout information. In an example, output data includes RSVP text to be presented to user 130. In an example, output data includes content generated in response to an instruction request such as supplemental content, navigation to a specified location of the content (e.g., a section of an insurance policy, contract, and the like), or control settings associated with the display of the content, initiate, change, pause or stop a command associated with the content (e.g. pausing the displayed content, resuming the displayed content, scrolling through the content, and the like).

In some embodiments, external data source 132 is implemented as a data source configured to receive query data from communication module 112, process the query data to generate result data, and provide the result data to communication module 112. In these embodiments, external data source 132 is implemented as a database that includes content information, such as for example images, text (e.g., books, articles, encyclopedia entries, blog posts, and the like), videos, metadata (e.g., relationships between images, texts, videos, and the like), and the like. In an example, external data source 132 is a database including company guidelines, sample insurance policies, explanations of insurance policies, a glossary of terms associated with insurance policies, metadata about the relationship between the terms within the glossary of terms and one or more sample insurance policies, and the like. In other embodiments, external data source 132 is implemented as a third party information source, such as an online encyclopedia, image server, video server, dictionary, and the like.

FIG. 5 illustrating an exemplary use case for presenting supplemental content to a user based on behavioral feedback, according to an embodiment. In FIG. 5, use case 500 includes user device 502 and user 510. In FIG. 5, user device 502 includes content display 504 and supplemental content display 506 based on user behavioral feedback.

In some embodiments, the gaze of user 510 can be characterized by first gaze line 512 and second gaze line 514. Use case 500 can include additional, fewer, or differently arranged components than those illustrated in FIG. 5.

In some embodiments, user device 502 is implemented as a computing device configured to: generate content data configured for presentation on a display of a user computing device, transmit the content data to the display of the user computing device for display on the user computing device, collect by a tracking sensor module behavior data of the user sensed by the tracking sensor module, generate engagement data based on the collected behavior data, determine supplemental content configured for presentation on a display of the user computing device and display the supplemental content to the user on the user computing device.

In an example and referring to FIGS. 1 and 3, user device 502 is configured in a manner substantially similar to user device 110 and user device 310. In these embodiments, content display 504 is implemented on at least a first portion of a user interface associated with user device 502 and configured to display content. Further to these embodiments, supplemental content display 506 is implemented as a second portion of a user interface associated with user device 502 and is configured to display supplemental content associated with content being displayed by content display 504.

In operation, user device 502 displays content. In some embodiments, user device 502 monitors the behavior of user 510 in order to generate behavioral engagement data. In an example and referring to FIGS. 1 and 3, tracking sensor module 120 controls tracking sensor 118 and begins to track the movements of the user 130 in order to generate behavioral data, and provides the generated sensor data to tracking module 118. In some embodiments, user device 502 retrieves supplemental internal content data from a storage device (not shown) and supplemental external content data from an external data source (not shown), generates the supplemental content, and displays the supplemental content on the display 504 based on the behavioral data. Further to this embodiment, behavioral data is the gaze of user 510 which is characterized by first gaze line 512. Further to this embodiment, the supplemental content is relevant to the portion of the content within the first gaze line 512.

In an embodiment, the behavioral engagement data can be assigned a value, which can represent an amount of time that the user's gaze is directed toward an item or away from the user interface. For example, if the user is gazing an item for more than one second, the user may not understand the item. In another example, if the user is gazing away from the user interface for more than one second, the user may be bored or distracted. In the exemplary embodiment, this threshold value is set at one second, but any time period can be used. When the value is above this threshold value, the system can query for supplemental content that is related to the content being displayed when the user was gazing for a long period of time or gazing away. A fixation for reading text may be about 200 ms in duration, so a threshold value can be based upon this value, whereby a threshold can be established at about 500 ms, 1 second, or 2 seconds. When detecting whether a user's eyes are distracted away from the displayed content, a different threshold value can be used, which can be established at 1 second, 2 seconds, 3 seconds, or 4 seconds.

In another embodiment, behavioral data is expression data and the content processing module can assign a state of the user based upon the expression data. In this embodiment, state is associated with the content that was being displayed when the expression data was captured. The expression sensor data is analyzed to determine whether any micro-expressions are associated with a particular state, such as disgust, anger, fear, sadness, happiness, surprise, amusement, contempt, embarrassment, anxiety, guilt, pride, relief, contentment, pleasure, shame, confused, distracted, upset, or content. If the state is content, then the content processing module will continue to present the content or present the next portion of content. If the user is associated with another state, the content processing module will query for supplemental content to display to the user, where the supplemental content is associated with the content that was associated with the determined state and the content that was being displayed when the expression data was captured.

In some embodiments, user device 502 may then detect that user 510 looks away from the content display 504 and towards supplemental content display 506, as characterized by second gaze line 514. In these embodiments, the generated behavioral data is used by user device 502 to determine that the user wishes to view information supplemental to the text being displayed on display 504.

In some embodiments, user device 502 proceeds to pause the display of content on display 504, generate supplemental content, and display the supplemental content on supplemental content display 506. In these embodiments, as user 510 views content on display 504, user device 502 may analyze the generated emotional state data and detect that user 510 is feeling confused. Further to these embodiments, user device 502 may then proceed to pause the display of content on display 504, generate supplemental content, and display the supplemental content on supplemental content display 506.

In an example, user 510 is consuming content on a life insurance policy. In this example, the information is displayed to user 510 via display 504. As user 510 consumes the content, user device 502 observes user 510 and determines that user 510 is confused by a portion of the content that contains life insurance information. In this example, user device 502 then generates supplemental content for display on supplemental content display 506. Further to this example, the supplemental content includes information relevant to the portion of the content being displayed when the user state is detected, e.g. a definition for the term, other life insurance polices, cost of the policy and the like.

FIGS. 6A and 6B illustrate exemplary use cases for presenting supplemental content to a user based on behavioral feedback, according to another embodiment. In FIG. 6, use case 600 includes user device 602 and user 610. In FIG. 6A, user device 602 includes media display 604 and supplemental content pop-up 606. In FIG. 6A, the gaze of user 610 can be characterized by fixed gaze line 612. In other embodiments, use case 600 can include additional, fewer, or differently arranged components than those illustrated in FIG. 6A.

In some embodiments, user device 602 is implemented as a computing device configured to display said content to user 610, generate behavioral data based on the behavior of user 610 as the content is being displayed, to determine if supplemental content is needed based on the behavioral data, and to generate supplemental content based on external and/or internal supplementary data that is relevant to the content being displayed. In an example and referring to FIGS. 1 and 3, user device 602 is implemented to function in a manner substantially similar to user device 110 and user device 310. In other embodiments, media display 604 is implemented as a first portion of a user interface associated with user device 602. In yet other embodiments, supplemental content pop-up 606 is implemented as a second portion of a user interface associated with user device 602 and configured to display supplemental content associated with content being displayed by media display 604.

In operation, content is displayed on user device 602. User 610 proceeds to consume the content, and the gaze of user 610 is characterized by fixed gaze line 612. User device 602 then monitors the behavior of user 610 in order to generate behavioral engagement data. In an example and referring to FIGS. 1 and 3, tracking sensor module 120 is controlled by tracking module 118 and begins to track the movements of the of user 130 in order to generate behavioral sensor data, and provide the generated sensor data to tracking module 118. Further to this example, tracking module 118 processes the behavioral sensor data into behavioral engagement data.

In some embodiments, user device 602 may then detect that user 610 looks fixedly at a particular area displayed on media display 604, as characterized by fixed gaze line 612. In these embodiments, the generated behavioral engagement data is used by user device 602 to determine that the user wishes to view information supplemental to the text being displayed on media display 604. User device 602 proceeds to generate supplemental content and to display the supplemental content relevant to the content being displayed by media display 604 on supplemental content pop-up 606.

In FIG. 6B, use case 601 includes user device 603 and user 611. In FIG. 6B, user device 603 includes media display 605 and activatable content 607. In FIG. 6A, the gaze of user 611 can be characterized by fixed gaze line 613. In other embodiments, use case 601 can include additional, fewer, or differently arranged components than those illustrated in FIG. 6B.

In some embodiments, user device 603 is implemented as a computing device configured to display said content to user 611, generate behavioral data based on the behavior of user 611 as the content is being displayed, to determine if supplemental content is needed based on the behavioral data, and to generate supplemental content based on external and/or internal supplementary data that is relevant to the content being displayed. In an example and referring to FIGS. 1 and 3, user device 603 is implemented to function in a manner substantially similar to user device 110 and user device 310. In other embodiments, media display 605 is implemented as a first portion of a user interface associated with user device 603.

In operation, content is displayed on user device 603. User 611 proceeds to consume the content, and the gaze of user 611 is characterized by fixed gaze line 613. User device 603 then monitors the behavior of user 611 in order to generate behavioral engagement data. In an example and referring to FIGS. 1 and 3, tracking sensor module 120 is controlled by tracking module 118 and begins to track the movements of the of user 130 in order to generate behavioral sensor data, and provide the generated sensor data to tracking module 118. Further to this example, tracking module 118 processes the behavioral sensor data into behavioral engagement data.

In some embodiments, user device 603 may then detect that user 611 looks fixedly at a particular area displayed on media display 605, as characterized by fixed gaze line 613. In these embodiments, the generated behavioral engagement data is used by user device 603 to determine that the user wishes to view information supplemental to the text being displayed on media display 605. In this example, the user 611 is directing attention to activatable content 607. Activatable content may be a drop-down menu (as shown), a hyperlink, or other content that can change or present a new feature, such as content that can be clicked or activated with a mouse or cursor. Upon detecting fixed gaze line 613 at the activatable content 607, the activatable content 607 is activated. In this example, the activatable content 607 presents a drop-down menu 617 when activated. Upon detecting a fixed gaze line 615 at the drop-down menu 617, the item on the drop-down menu associated with the fixed gaze line can be activated (e.g., selected from a drop-down menu).

FIG. 7 is a flow chart of an exemplary method for presenting supplemental content to a user based on behavioral feedback, according to an embodiment. In some embodiments, said method may be executed in system hardware and software architectures similar to those described in FIGS. 1-6, above.

In FIG. 7, process 700 begins at step 702. At step 702, a user powers a user device on. In an example and referring to FIGS. 1 and 3, user 130 powers on user device 110. In an example, user device 110 is powered on when user 130 inputs a command via an input/output device. In some embodiments, the user device loads a content processing module, a communication module, an input/output module, and a tracking module from the user device memory into the user device processor, which instructs the device processor to execute the method described herein. Process 700 proceeds to step 703.

At step 703, the user device can determine if the user is authorized via an authentication module 126 executed by a processor on the user device. The authentication module of the user device may communicate with the external data source to authorize the user, or the authentication module 126 can authorize the user locally on the user device. Process 700 proceeds to step 704.

At step 704, upon receiving a request to present content received, the input/output module is loaded into memory by the processor and instructs the processor to execute instructions to display content. Process 700 then proceeds to step 706.

At step 706, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to provide command data to the communications module to retrieve content data from an internal and/or external data source. The communications module then instructs the user device processor to provide query data to the internal and/or external data source via the user device. The internal and/or external data source receives the query data, processes it, and returns result data to the communications module. The communications module then carries out instructions on the user device processor in order to process the result data and provide the content data to the communications module. The communications module then carries out instructions on the user device processor to display the content. Process 700 then proceeds to step 708.

At step 708, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to send command data to the tracking module including instructions to activate the tracking. At this step, the processor carries out instructions to prepare the user device to track the behavior of the user, such as for example the head movement, gaze and/or micro expressions of the user. Process 700 continues to step 710.

At step 710, the tracking module uses behavioral sensor data from the tracking sensor (e.g., images, gaze path curves, micro expressions, head movement, head position and the like) to determine the level of behavioral engagement and/or emotional state of the user has with the content being displayed by the user device. The processing module then provides the behavioral engagement and/or emotional state data to the content processing module. Process 700 continues to step 7012.

At step 712, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to process the behavioral engagement data and/or the emotional state data to determine if supplemental content is required. At this step, the content processing module determines if the behavioral engagement data of the user indicates that the user is focusing his or her gaze on the content, or whether they have looked away or shown some other indicator of disengagement from the content. If the content processing module determines the user has disengaged with the content, the content processing module may pause the display of content on the user device and generate command data to retrieve supplemental data associated with the content being displayed on the user device. If the command processing module determines that supplemental content is required, process 700 proceeds to step 706. Otherwise, process 700 proceeds to step 710.

At step 716, the user decides if they want to continue to view content, if the user continues to view content the process 700 proceeds to step 716. If the user decides they do not want to continue to view content, the process 700 ends.

In the instant application, the inventors have improved over previous content providing systems by dynamically providing supplemental content based on user behavior. In particular, using the tracking sensor module and/or the tracking module, the system can continuously and automatically monitor the behavior of a user consuming a content data to ascertain whether the user is ready for supplemental content data. Only when the user's behavior indicates a need for supplemental content data, the invention gathers the supplemental content data from the internal and/or external source and modifies the display to show the supplemental content data. When the user's behavior shows no supplemental data is being requested, the displayed content data remains unchanged. The process is performed by using tracking sensor modules and tracking modules that collect behavior data based on any one or more of user's head movement, expressions, eye movement, and gesture, generate an engagement data based on the collected behavior data and translating such gesture data into instructions that reflect whether supplemental content data is being requested. In so doing, by permitting supplemental content data to be dynamically provided in response to a user's behavior, the system's ability to display information and interact with the user are improved.

Moreover, by only supplying supplemental data based on user's behavior, the system described herein is able to efficiently provide the requested information seamlessly to the user allowing a more efficient way to consume the content data and supplemental content data from the user's perspective as well as from a computing standpoint. The user can be more efficient by not having to enter commands or seek supplemental content data other than by looking at the display and making a simple head or eye movement, other gesture, or simply change expressions. From a computing perspective, the system is more efficient in that it limits the use of memory and information transfer and processing to only what the user is able to consume, thus avoiding processing or transferring unnecessary information prematurely.
